Processing for Android

The first thing I should mention is that I figured very little of this out for myself. Everything I've learned I learned from smart people on the web. I link to them where appropriate. You should plan on checking out the Android - Processing Wiki regularly. Any updates will show up there long before they end up here.

AK Eric Blog - He has some great Android Processing tutorials including implementing Multi-Touch (as an aside, metabog added to AKEric's multi-touch code).

Adding Sound - This is a discussion over on the Processing Forums. Good stuff here. The standard Processing Library Minim will not work on Android.

Android Processing Widgets - The Audio forum discussion led me to this. It's a library that will allow you to do some pretty cool stuff pretty easily. Including playing audio or video files as well as create a number of different button types.
